An insect that can infest and damage hundreds of hectares of maize fields, literally overnight, is sweeping across Asia – alarming smallholder farmers and threatening livelihoods – but the damage can be limited, the UN’s Food and Agriculture Organization (FAO) reported today. Fall Armyworm is native to the Americas. However, since 2016 it has been aggressively moving ever eastwards, sweeping across Africa, and making landfall for the first time in Asia last summer. Fall Armyworm (FAW) was first detected in India in July 2018 and by January of this year, it had spread to Sri Lanka, Bangladesh, Myanmar, Thailand and China’s Yunnan Province.
National Environmental Science Programme (Australia). Threatened Species Recovery Hub.
New research by the Threatened Species Recovery Hub has shown that invasive or pest species are a problem for 1,257 threatened species in Australia, or about four out of five species. The research which has been published in the scientific journal Pacific Conservation Biology also identified the top ten invasive species based on how many threatened species they impact. Lead researcher Stephen Kearney from the University of Queensland said many people may be surprised at which species top the list. “Rabbits, a plant root disease and feral pigs are the top three pest species impacting Australia’s threatened species,” Mr Kearney said.
Smithsonian Environmental Research Center.
More than 50 non-native species have found their way to the Galápagos Islands, over 10 times more than scientists previously thought, reports a new study in Aquatic Invasions published Thursday, March 28. The study, a joint effort of the Smithsonian Environmental Research Center, Williams College, and the Charles Darwin Foundation, documents 53 species of introduced marine animals in this UNESCO World Heritage Site, one of the largest marine protected areas on Earth. Before this study came out, scientists knew about only five.

Grass carp, one of four species of Asian carp, has the potential to disrupt the Great Lakes ecosystem and economy unless their spread is stopped, according to a report released by Fisheries and Oceans Canada with support from the Great Lakes Fishery Commission and the Ontario Ministry of Natural Resources and Forestry. The socio-economic study concludes that, in addition to the significant ecological threat that is posed by the presence of grass carp in the Great Lakes, there would also be economic, social and cultural ripple effects. The full report can be viewed here (PDF | 1.34 MB).

Great Lakes Commission.
Aquatic invasive species inflict millions of dollars of ecological and economic damage to the Great Lakes, with impacts on coastal industries, water quality, native fish and wildlife and human health. Recently, Blue Accounting, in partnership with state and federal agencies, launched a new suite of web-based resources and tools to support early detection of aquatic invasive species in the Great Lakes. The earlier new aquatic invasive species are detected, the easier and less expensive it is to avoid potentially devastating consequences of a large invasion. The new tools released by the Blue Accounting initiative help target efforts to focus on high-risk species and locations across the 11,000 miles of shoreline and 94,000 miles of surface area that make up the Great Lakes basin.
Nordic Council of Ministers. Nordregio.
One of the projects supported by the Arctic Co-operation programme of the Nordic Council of Ministers is launching a major campaign to raise public awareness of the threat posed to the Arctic by alien species travelling with tourists and other visitors. Nordregio takes part in the campaign in its capacity as secretariat for the Nordic-Arctic programme. “Are you travelling alone?” asks an animated polar bear in a new campaign video as he examines some clothes, shoes and equipment belonging to the travellers that step off boats and airplanes that bring them to the Arctic. The video is launched together with travel operators, airline companies, travel agencies and tourist offices that have the Arctic as a travel destination, as well as national and regional authorities to make sure it reaches as far as possible – hopefully unlike the alien species it aims to warn against.
